Fix -Wlarge-by-value-copy option handling in the driver. CC1 supports only the joined format. llvm-svn: 156161

// RUN: %clang -### -Wlarge-by-value-copy %s 2>&1 | FileCheck -check-prefix=LARGE_VALUE_COPY_DEFAULT %s

Warn about -Wno-foo where foo is an unknown warning option. This is helpful for subtle misspellings such as -Wno-unused-command-line-arguments instead of -Wno-unused-command-line-argument. Also fix the diagnostic messages to properly handle -Wno- options. Previously, the positive version was always emitted (i.e., -Wfoo was emitted for -Wno-foo). rdar://11461500 llvm-svn: 156937

Tweek r156937 a bit so that the suggestions are correct. llvm-svn: 156938

// CHECK: unknown warning option '-Wno-unused-command-line-arguments'; did you mean '-Wno-unused-command-line-argument'?
Add a test for -Warc-abi as requested by Fariborz. llvm-svn: 166540

// FIXME: Remove this together with -Warc-abi once an Xcode is released that doesn't pass this flag.

Typo. llvm-svn: 170613
